About the 36mm Rolex Explorer

The Explorer is one of the very few Rolex models to get smaller again. It was 36mm for fifty-seven years, grew to 39mm in 2010, and then returned to 36mm in 2021, which is close to unheard of in a catalogue where sizes have moved in one direction for decades. That reversal is the reason this page exists, and it is the context a buyer needs before choosing between the sizes now on offer. Everything we stock is checked by our watchmakers and carries the WatchGuys 2 Year Warranty. Our Explorer reference breakdown sets out every reference and production date.

Fifty-Seven Years at 36mm

From the 6350 in 1953 through to the 114270 discontinued in 2010, every Explorer I was 36mm. That covers the entire vintage era, the 1016's twenty-six year run, and the first two modern references. No other Rolex sports model held a single case size for that long, and it is why 36mm is not simply a size option on the Explorer but the size the design was drawn around. The dial layout, the proportions of the numerals, and the relationship between case and bracelet were all resolved at 36mm across five decades of refinement. Anything else is a departure from it rather than a variation on it.

The 39mm Detour

In 2010 Rolex replaced the 114270 with the 214270 at 39mm, following the industry-wide move toward larger cases. It was not a straightforward success. Early examples drew consistent criticism for hands that looked short against the enlarged dial, a proportion issue Rolex addressed partway through the run by lengthening them. The 39mm case itself was well made and many owners liked it, but the reference never quite settled the way the 36mm ones had, and it remains the outlier in the model's history. It is also frequently listed loosely as an Explorer without the size specified, which catches out buyers assuming any modern Explorer is 36mm.

Why Rolex Went Back

The 124270 arrived in 2021 and returned the Explorer to 36mm, and the reasoning is not hard to read even though Rolex has not stated it. Taste had shifted back toward smaller cases across the industry, the 39mm reference had never generated the affection its predecessors did, and 36mm is what the Explorer had always been. What Rolex did not do was simply reissue the old watch. The 124270 brought a current-generation movement with a much longer power reserve and a redesigned bracelet, so it is a modern watch in a historical size rather than a retro exercise. Two years later Rolex added a 40mm version alongside it, which means both sizes now coexist rather than one replacing the other.

Every 36mm Reference

The list is long because it covers seven decades. On the vintage side, the 6350, 6150, and 6610 from the 1950s and the 1016 that ran from 1963 to 1989, all covered in our vintage Explorer collection. The modern era begins with the 14270 in 1989 and continues through the 114270 until 2010. After the 39mm gap, the 124270 returned in 2021, joined by the two-tone 124273 covered in our two-tone Explorer collection. Every one of those is 36mm. The only Explorer I references that are not are the 39mm 214270 and the 40mm reference introduced in 2023.

How 36mm Actually Wears

Larger than the number suggests, for two reasons specific to this watch. There is no date, which means no aperture and no Cyclops interrupting the dial, so the full width reads as usable dial space rather than being partly given over to a window. And the bezel is smooth, narrow, and domed rather than a broad rotating unit, so almost the entire case diameter is dial. A 36mm Explorer therefore presents more dial than a 36mm watch with a date and a thick bezel would, and considerably more than a diver of the same diameter. Buyers coming from a 40mm sports watch usually find it reads as smaller but not small, which is a different thing.

36mm Explorer Price

The size spans the widest price range in the family because it spans the most references. Discontinued modern references, the 14270 and 114270, are the accessible end and among the most affordable routes into a steel Rolex sports watch at all, generally starting in the mid to high single digits. The current 124270 trades close to its retail figure. The two-tone 124273 sits above it on gold content. At the top, vintage 36mm references run well into five figures with correctness rather than size driving the number. Nearly everything in this size falls inside our Rolex watches under $20,000 range.

36mm or 40mm?

Both are current, both use the same movement, and neither is the compromise. The 36mm is the historically correct size, the one the design was resolved around, and the more versatile across wrist sizes. The 40mm gives more presence and suits buyers who find 36mm too restrained, particularly anyone coming from a Submariner or GMT-Master II. The practical test is whether you want the Explorer to read as a tool watch or as a dress-adjacent one, because the same design does both depending on the diameter. If you are undecided, the 36mm is the safer purchase: it has the deeper history, the wider secondary market, and it is what most people picture when they think of the model.

Why Buy a 36mm Explorer From WatchGuys

Seven decades of 36mm references, one 39mm reference sitting in the middle of them, and listings that frequently say Explorer without saying which. Getting the size right is the first job here, and on the older references correctness matters as much as the number does.

Common Questions

36mm Rolex Explorer FAQ

• Which Rolex Explorer References Are 36mm?

  Almost all of them. On the vintage side, the 6350, 6150, and 6610 from the 1950s and the 1016 that ran from 1963 to 1989. In the modern era, the 14270 from 1989 and the 114270 until 2010, then the 124270 from 2021 and the two-tone 124273 alongside it. The only Explorer I references that are not 36mm are the 39mm 214270 and the 40mm reference introduced in 2023.

• Why Did Rolex Go Back to 36mm?

  Rolex has not said, but the reasoning reads clearly enough. Taste had shifted back toward smaller cases, the 39mm reference never generated the affection its predecessors did, and 36mm is what the Explorer had always been. What Rolex did not do was reissue the old watch: the 124270 brought a current-generation movement with a much longer power reserve and a redesigned bracelet, making it a modern watch in a historical size rather than a retro exercise.

• Is the 39mm Explorer Discontinued?

  Yes. The 214270 ran from 2010 to 2021 and was replaced by the 36mm 124270. It remains the only 39mm Explorer and the outlier in the model's history. Early examples drew consistent criticism for hands that looked short against the enlarged dial, which Rolex addressed partway through the run by lengthening them. It is well made and has its supporters, but it never settled the way the 36mm references did.

• How Much Is a 36mm Rolex Explorer?

  The size spans the widest range in the family. Discontinued modern references, the 14270 and 114270, start in the mid to high single digits and are among the most affordable routes into a steel Rolex sports watch. The current 124270 trades close to its retail figure, and the two-tone 124273 sits above it on gold content. Vintage 36mm references run well into five figures, with correctness rather than size driving the number.

• Does a 36mm Explorer Wear Small?

  Less than the number suggests. There is no date, so no aperture or Cyclops interrupts the dial, and the bezel is smooth, narrow, and domed rather than a broad rotating unit. That means almost the entire case diameter reads as dial, considerably more than a 36mm watch with a date and thick bezel would show. Buyers coming from a 40mm sports watch generally find it reads as smaller but not small, which is a different thing.

• Should I Buy the 36mm or the 40mm?

  Both are current, both use the same movement, and neither is a compromise. The 36mm is the historically correct size and the more versatile across wrists. The 40mm gives more presence and suits buyers coming from a Submariner or GMT-Master II who find 36mm too restrained. If you are undecided, the 36mm is the safer purchase: deeper history, wider secondary market, and it is what most people picture when they think of the model.
